Battery Fully Charged Light?

Hi,

    I currenty have two batteries with my Spark, each displaying quite different fully-charged behavior. One of them is exactly like in the Spark manual, all 4 LEDs are off after ~1hr of charge. The other one is kind of confusing, as it goes in cycle like '1-2-3-4--wait--1', making it looks like it is still in the final stage of charging, but with a blink of LED-1 after. I cannot find this behavior in the manual. The battery is flying just fine. (not full 15 minutes, but not too short either) Is there anything wrong with my battery?

How is the votalge reading? Also make sure it sits firmly when charging and the contacts are clean.

Would you please make a small video showing the situation you mentioned?
Besides, after it's fully charged, please check the battery info via APP and upload a screenshot here, thank you very much!

I tried to leave it charging in this state for 8 hours, and it never ends.

What does the battery level read in the dji go 4 app when you plug it into the spark and connect?

Otherwise, it definitely seems to be faulty, raise it with DJI support if you haven't already.

If the Led status does not change back to normal, it acts as the video all the time, then it needs to be sent in for evaluation.
You could contact our support here to get a case number and send it in: http://www.dji.com/support/product

Sorry for any trouble caused.
Would you please upgrade aircraft  then check again?
Besides, may I know where you're located recently and where you purchased the batteries?

I bought Spark in the united stated but I am traveling with it now. I was actually in Shenzhen, 2km away from DJI HQ 2 days ago.

I have updated the spark firmware and DJI4 app while in Shenzhen. The battery light still behaved like the undocumented behavior for ONE battery. The other battery is normal.

I purchased a battery from BestBuy and it is exhibiting the same behavior as described above. I’m returning it.
